colorSENSOR CFO
12 You can choose between Sphere (∆E), Cylinder (∆L; ∆ab), Box (cuboid, ∆L; ∆a; ∆b) and Classifica -
tion as distance model , see 5.6.4.1 .
Depending on the distance model selected, it is possible to set the tolerance values (11) to 1 .. 3.
These values describe the size of the tolerance space around the learned color.
Within a color group, the same distance model and the same tolerance values are used for all learned
colors.
No tolerance parameters are set for
Classify
, because the currently measured color is always asso-
ciated to the color saved in the color table with the smallest distance to the measured color , see 2.4 .
When teaching a new color group, the values selected under Color group settings , see 5.6.4 (Color
group) are used for the distance model and the tolerance values (11).
Example: Cylinder distance model
Half height (L) = 8
Radius (a/b) = 4
These can be manually adjusted in the edit mode of the group between 0 ... 50.
13 The maximum name length is 64 characters and may consist of only alphanumerical characters (a-z,
A-Z, 0-9, no foreign character attributes), spaces and the special char-#,.().
